提出了语音信号的快速实值离散Gabor变换(RDGT)方法,讨论了由RDGT系数计算语音复谱图值、语谱图生成和语音信号的快速重建问题。并给出了实例。%In this paper we present fast real-valued discrete Gabor transforms RDGT for speech signal representation and develop a new method to compute the speech complex spectrogram and the speech spectrogram generation from the RDGT coefficients. The fast reconstruction of speech signal is also discussed and some experimental examples are given.
